Personally, I think these are hilarious. This person is punishing himself for his laziness and/or incompetence. If he can't be bothered to post anything other than hello, then he won't be getting his issue fixed, either.
Obvously there's one of 3 problems here with hiwa_80:
1. He's unable to type or continue for some physical or technical reason on the computer or his ISP;
2. He's voluntarily retarded;
3. He's an immature simpleton that thinks nothing of wasting other people's time and squanders the generous offers of others free help, most likely because he has no life of his own.
